【摘要】 采用微反-色谱联合装置，在反应压力为0．5－3．5MPa，质量空速（WHSV）为0．5－2．5h－1，氢烃摩尔比（H2／nC5）为1－5，反应温度250～290℃的条件下考察了反应条件对Pt／HM催化剂性能的影响。用正交试验法确定了正戊烷异构化最佳反应条件，使正戊烷转化率为7185％，反应选择性为96．07％，异戊烷收率为69．03％，液收率97．53％。并对催化剂连续运行1000h，结果表明催化剂性能稳定。更多还原

【Abstract】 Using micro-chromatographic combination unit, under conditions of reaction pressure being 0.5-3.5Mpa, mass space velocity (WHSV) 0.5-2.5h-1, hydrogen/hydrocarbon mole ratio (H2/nC5) 1 -5, reaction temperature 250-290oC, the effectiveness of reaction conditions to the property of Pt/HM catalyst was investigated. The premium reaction conditions of n-pentane isomerization are determined with orthogonal test, making the percent conversion of n-pentane to 71.85%, reaction selectivity to 96.07%, i-pentane yield to 69. 03% and liquid yield to 97.53%. The catalyst is continuously running for 1,000h, result shows that the catalyst property is stable.更多还原
